cles to be operated upon are moved beneath the proj ecting'vbristles thereof, the object of l the invention being' the production of a brush in which the bristles may be renewed as desired.

This object is attained by the mechanism illustrated in the accompanying drawings.

Original No. 1,618,742, dated February 22l 1927, Serial No. 94,348, led. March 12, 1926. Application for 192s. serial Np. 318,290.

k Figure Qrep'resents a plan of two bristlesupporting units with their corrugations staggered andrlshowing one of the grooved i clampingyplates coacting with the outer unit.

Similar characters indicate like parts throughout the severalfigures of the drawings, .Y

In the drawings, 10, 10 are the side members of a frame having pivoted, at 11, to they ends thereof, theU-shaped connecting members 12.

Each side member consists of a plate 10 having disposed on the inner face thereof two channel bars 13 and 14, secured to the plate y10 bv rivets 15. 'f

These :channel bars 13 and 141 form oppo- .sitely disposed grooves in `which.y are disposed a pluralitysof `bristle-supporting units 16 havingiprojections 17- at the opposite ends thereof extending into vsaid grooves.

Eachl brstlesupporting unit 16 is composed of two plates 18 and 19, theupper ends of which are flat and in contact, as shown in Figs. 5 and 6, while the lower portions thereof have corrugations 20 formed therein.

These corrugations are oppositely disposed inpairs vforming sockets 21 in which a plurality of bristles 22 are positioned.

The bristles 22 extend to the inner end of each socket21 and by this end are prevented frommoving inwardly` Each corrugation has any indentation or` in the opposite edges thereof, and the plate 18` has at its opposite edges projecting clips 25 which are adapted to be bent over'the plate 19 and positioned in the notches 24.

The plates 18 and 19 are also secured together by rivets 26 in theopposite ends of said l plateswj The bristle-supporting units 16 are adapted to be inserted in the grooves of the channel bar 14 in any desired number, 'andv at the opposite ends of the series of units 16 are disposed @lanqgifigAv bars 27; theinner faces 91E which are corrugated to fit the corrugations in the bristle-supporting units 16.

When the series of units 16 is thus disposed within the grooves of the channel bars 14 and the clamping plates 27 are disposed at the opposite ends thereof, all of the units are forced toward each other and clamped by means of an adjusting screw 28, threaded to each Ushaped connector 12.

hould the bristles of any of the units become unduly worn the U-shaped connecting members 12 may be moved about their pivots 11 and the bristle-supporting units 16 removed and new ones inserted to replace those which have become unduly worn.

In the grooves in the upper channel bar 13 are disposed cross bars 29 having bolts 30 extending upwardly therefrom through slots 31 in a stationary part 32 of a machine, the upper ends of the bolt 30 having threaded thereto clamping nuts 33.

These bars 29 may be adjusted endwise of the channel bars 13 and then clamped to the stationary part 32 in any desired position.

The stationary part 32 is some portion of the frame of a machine disposed over a reciprocating table on which is mounted the article to be acted upon by the projecting bristles 22 of the various units 16.

One use of the brush is in connection with a paper coatingr machine in which coloring matter is applied to one face of a roll of paper by rotary brushes, the paper then passing over a bed and under a plurality of brushes of the type herein shown and described, these brushes being'reciprocated over the coated face of the paper in different directions and spreading the coloring matter evenlyover the entire face.

As the machine itself forms no part of the present invention, it is deemed unnecessary to illustrate the same in detail. l

iVhile in Fig. 1 the corrugations of the various units 16 are shown alined, if desired these corrugations may be staggered, as shown in Figs. 1fL and 9, so that the bristles in one unit will be opposite the spaces between the group of bristles in the next unit. When the corrugations are thus staggered, with their' backs intermeshed, as shown in Figs. 1l` and 9, the compressing together of the units, as by the clamping plates 27, combines them all into a single larger brush, in which the units 16 are securely and rigidly interlocked with each other for any use or manner of operation of the brush as a whole that may be desired. i

Owing to the projections 17 extendinginto the grooves of the channel bars 14, there can be no vertical movement of the various units, and owing to the clamping screw 2S, all movement of these units endwiseof the frame 10, 12, is eifectually prevented.

At the same time, when it is desired to replace the worn bristle-supporting units16 by others, this can be readily accomplished in an obvious manner.

This makes a very simple form of brush for heavy machines providing means whereby it may be securely clamped in position to a stationary part of the frame.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, I claim:

. 1.
